Wood Adhesives Based on Natural Resources: A Critical Review Part I. Protein-Based Adhesives
Manfred Dunky
Abstract
This series of critical reviews on Wood Adhesives Based on Natural Resources (in total four parts) describes the experience and actual status of wood adhesives based on natural resources and gives an outlook into the future of these materials. Desite boundless results and papers in the development, purely naturally based wood adhesives are in industrial use only in negligible amounts; therefore this review series also reports on combinations of naturally based adhesives with synthetic components, such as modifiers or crosslinkers.<br/> Part I of this series concentrates on general topics and questions related to wood adhesives based on natural resources, such as systematic overview on the various types of naturally based wood adhesives, including cases where the adhesive is not applied separately but is used in situ , originating from the various components of the wood material. As a first product group, proteins from plants and animal sources and their use as wood adhesives will be described in this Part I.
